Spearman correlation analysis of OLS-characteristics versus serum parameters.

	PTH n=14	APH n=14
OLS-porosity	0.66**	n.s. (p=0.195)
OLS-density	0.68**	n.s. (p=0.225)
OLS-area	0.71**	0.58*
OLS-perimeter	0.64*	n.s. (0.087)
OLS-aspect ratio	n.s. (p=0.750)	n.s. (p=0.510)

Data show Spearman correlation coefficients.

^**p<0.01,

^*p<0.05, n.s. not significant

Positive correlation coefficients indicate that one parameter is increasing with the increasing other parameter.
